Abstract

ABSTRACT The genus Meristotheca J. Agardh is the second largest in Solieriaceae with 13 species widely distributed whose thalli are mainly flattened. On the basis of molecular and morpho-anatomical evidence, M. spinella Núñez-Resendiz, Dreckmann & Sentíes, sp. nov. is the second species in the genus with cylindrical axes to be described from the southwestern Gulf of Mexico. rbcL sequences and genetic distance values indicate its separation from other species within Meristotheca and from other morphologically similar species occurring in its known distribution range as M. cylindrica Núñez-Resendiz, Dreckmann & Sentíes. The numerous short branchlets that cover the margins of main axes and branches, among other relevant anatomical and reproductive characters, is the main difference from M. cylindrica, its sister species.

摘要分生苔属(Meristotheca J. Agardh)是水芹科第二大属，分布广泛，有13种，菌体以扁平为主。根据分子和形态解剖学的证据，M. spinella Núñez-Resendiz, Dreckmann & Sentíes, sp. nov.是在墨西哥湾西南部描述的第二个具有圆柱形轴的属物种。rbcL序列和遗传距离值表明它与分生膜科的其他物种以及在其已知分布范围内的其他形态相似的物种如M. ica Núñez-Resendiz, Dreckmann & Sentíes有区别。在其他相关的解剖学和生殖特征中，覆盖主轴和分支边缘的许多短小枝是与其姊妹种白茅的主要区别。
